The formula for cost-benefit analysis is:

Where:

• CF_t is the cash flow at time t
• r is the discount rate (risk-adjusted)
• t is the time period

Data & Statistics

Comparison of Cost-Benefit Analysis Methods

Method	Advantages	Disadvantages
NPV	Easy to understand, considers time value of money	Sensitive to discount rate, doesn’t consider scale of projects
IRR	Overcomes NPV’s sensitivity to discount rate, considers scale of projects	Can have multiple IRRs, doesn’t consider cash inflows and outflows

Expert Tips

• Always use a risk-adjusted discount rate.
• Consider both tangible and intangible benefits and costs.
• Be consistent in your analysis; use the same method and assumptions throughout.
